Find the quadratic equation for y=x^2+6x-7

x = - 1 or x = 7

Step-by-step explanation:

From my understanding, y will be zero and you have to find the value of x.

Step 1: Middle term break

y = x² + 6x - 7

x² + 6x - 7 = 0

x² - 7x + x - 7 = 0

Step 2: Solve

x (x-7) + 1 (x-7) = 0

(x+1) (x-7) = 0

x = - 1 or x = 7

Therefore, the value of x is either - 1 or 7.
